Byobu is a light, powerful, text-based window manager based on GNU Screen. Using Byobu, you can quickly create and move between different windows over a single SSH connection or TTY terminal, monitor dozens of important statistics about your system, detach and reattach to sessions later while your programs continue to run in the background.

Byobu can be configured to run by default at every text login (SSH or TTY). That behavior can be toggled with the byobu-enable and byobu-disable commands.

In your remote ssh session type the following

byobu-enable

or

byobu-disable

Byobu displays two lines at the bottom of your screen. The upper one is the Caption line, and the lower one is the Hard Status

The Caption line shows your open windows, and highlights the one upon which you are focused, and optionally displays your user name, host name, IP address, and a hint that there is a Menu available if you press F9.

The Hard Status line consists of color coded output and symbols with configurable and dynamically updated facts, statistics, and information about the local system. See the Status Notifications section below for more information.

Some users may find the Hard Status line distracting. The byobu-quiet command will disable the display of the Hard Status. Append –undo to revert this configuration change.

Some other users may find both the Hard Status and Caption distracting. In this case, the byobu-silent command will disable both lines. Again, append –undo to revert the change.

Byobu provides a comprehensive, advanced set of commands bound to the F-keys on most keyboards.
